0:00So the new regulation is the disaster. It means one of the percent of the LMs that were trained these last three years would be illegal in Europe. It's not connected to the reality. The intent is good, but the limited puts on how to train a model and how to operate a model makes it in practice. Compared to what we do today, makes everything illegal. Welcome back to 20BC with me, Harry Stabings. And today we continue the deep dive into the world of AI.

3:10Alex, I am so excited for this. I've been looking forward to this one for a long time. I've been thinking with a couple of the AI shows. I can't wait to do this in person with Alex. So thank you so much for joining me today. Thanks, Harry. I would love to start with a little bit of context, because we're three startups in this point. So how did you first make your way into the world of startups? So 22 years ago I fell in love with a chatbot her name was CBL Really really I was you know summer night in Paris in my basement alone with my computer and I basically go in many directions Up to you I was Missed by this chatbot, you know the fact that the machine is trying to understand you Language and can generate some words and I was really really struck by this thing and I decided okay We just spend my life building chatbots And so I founded a company doing customer service bots 22 years ago very early And this is how I started this series of companies in the name can I ask you given it was 20 years ago And I know this is off schedule straight away But just how do you think about market timing stay when we started I thought child bots would become very very intelligent after Three four years and get to age I and replace humans in call centers and the more I worked on the problem The more I realized it was really really difficult to do that actually the first time we released the bots Europe was in 2004 to the French railway company and we were very very happy to have this customer and the deputy CEO tried it and she asked my name is wrong on the reservation.

4:37All bought and served. Hello wrong on the reservation and then we realized okay there is still a lot of work. It's not smart at all and so the more I worked on these things the more I realized it's not already yet. So suddenly for the last year, two years we reach a point where market time I mean, maybe finally finding the good, you know, where the product is ready and people that evolved to maybe 10 years after a series, people have changed. So maybe the market timing is now. So if we project forward and thinking of market timing, how did Nabila come to be and what was that a founding moment?

5:07I was sitting at a terrace at Facebook headquarters in Mendel Park, we joined Facebook through the acquisition of my second startup. And sitting at this terrace with a cocktail looking at the sunset, suddenly it reminded me of a scene in Silicon Valley, you know the show. Yeah, I love where they go on the roof at Hulley and there's these people doing barbecue and say yeah, we are Vest and rest And and I saw myself in this vest and rest Situation and after four years at Facebook. I certainly really it's okay It's time to go out and back to the arena and we've learned so many things at Facebook Yeah, I research it's time to try to push these things to the real world Can that's what we say the biggest takeaways from your time at Facebook and the AI research can plan so first things that amazed me when I arrived at Facebook is I thought old big companies were slow and actually when we arrived at Facebook in early 2015 there was maybe six thousand employees and it was going so fast and it was a machine very well all of the machine engineering was so efficient I learned it's possible to be that big and very very efficient and when you are in this vision there is nothing you cannot do just after I joined I started to work on a project that I wanted to hire 200 people to human concierge to train my but in real time it was not in the budget of course but like a week after I had a meeting with Mark and in about 10 minutes I challenged a little bit my ID and he said okay let's do that and I could hire 200 people in Manlo Park and when you have this speed and agility and limited resources of a company like Facebook at the time I was really shocked by this at Facebook.

6:39What did you learn from working with Mark? You mentioned that meeting there in the speed of decision making from him. Is there anything that you took away from working with him? Many things, one thing I like is spent not a lot of time outside the company You know, he had like 30 minutes meetings back to back from morning to evening and he prepared really well every meeting So you have to send in advance and like a short note about what decision you are expecting from him If you fail to send this document 24 hours, you know, by the minute before your meeting get canceled And so in many cases you arrive in for the theme is read your document is gather all the information that that I need So the meeting is very fast, you know, you will challenge what you ask for maybe and make a decision So this way to work I think there is much to learn I give you an example of that when I wanted to hire my 200 human Concierge my reasoning was we will train this AI it will work really well and we will steal business from Google in terms of Social like exactly what chip chat GPT made it in the time to come I prepared answers to every possible objection He could object about everything I was ready to say why my ID would work and I arrived at the meeting and first Minute it tells me Alex I agree with you.

7:48It will work so instead of hiring 200 concierts Let's hire one of the thousands and we will kill we go tomorrow and then I completely reverse my course and say no no no mark I'm actually I'm not sure if we work it would be crazy to hire one of the thousand people And I gave all my reasoning on the opposite sense like we should be careful this thing might not work and so on so very smart of him I don't know if it was on purpose but he learnt more about the truth of my projects attacking it from this direction this angle and it was very very interesting. Can I ask and we mentioned kind of an emblem of your third company what what with the prior ones that you've taken with you what didn't what you left behind and does it get easier?

8:27It's not getting easier you learn some lessons you don't do the same mistakes again hopefully but get new dangers you know new issues. The one I suffered from when I started Nambla is what I call the Kim Jong Un entourage trap. You see this video of Kim Jong Un visiting something and all the generals are around him with a notebook and everything you say will be written down if you fail to do that. I guess you deserve a pair of the next day and nobody of course will ever ever say I disagree with you or challenge any of these decisions. And starting my third company after two exits, I felt like my investors were always agreed, my team always agreed, people around us and so I wasn't challenged enough And then we made some early mistakes that probably were not challenged enough.

9:13What was the money mistakes? So when we decided to start in healthcare, we were a engineering team, you know, very strong in AI and engineering But not so much in healthcare and we made actually a good decision to start as a B2C healthcare company to learn. But then we lost our way a little bit and we went too far before realizing that it was not the right path and that we should go back to a B2B business model. We probably took too much time to make the decisions just an example. Can I ask you, what do you do that to stop the Kim Jong -un parrata or so, a problem? Like how do you surround yourself with people that do challenge you?

9:49What did you change? The solution first is I think it's with external people, you know, even my investors were too close to me, but if you go to people far as our way, they have less, were very successful and they have no incentive to please you and you get more information, more data from them. And, internally, it's a matter of just telling your team, okay, you should challenge our decisions and we did that a lot at Nebula and sometimes too much, you know, the challenge, everything after that. Also, after you make one or two mistakes, the team will more naturally come forward and this is before you reach the right level of the challenge.

10:22It's funny, one of my friends is Gustav Sodashram, who's a CPU at Spotify, and he says talk is cheap, and so we should do more of it. I want to start on where we are in terms of the landscape itself, and we look at the developments today, and I think shout GBT is brought around from a consumer excitement to a level that we haven't seen obviously in AI for years and years. Have there been fundamental developments in the last 18 months, technologically, that have led to where we are to stay with our excitement level, or is it the continuation of years of behind -the -scenes development? For the general public, it looks like a very big step function with huge advancement every 10 years.

10:57I think from the inside it's much more continuous. So for instance, Chad GPD, you know, he's based on GPT -4, which is based on GPT -3, who was released three years ago. GPT -3 is a large language model. It was invented before that, transformers, where the paper was released in 2016. The progress is continuous, but the public perception of it is very, very discontinuous. Can I ask you, what do you make of the VC hype cycle? What do you want to the teams around you and that true AIOG is think? When they say, see all the VCs just chasing everything in the AI? From our standpoint, it's really ridiculous.

11:33I've been building AI companies for 22 years, so I've seen these cycles several times. So after a while, you're not surprised anymore. The only thing you need to know is when to add or remove AI from your deck and you should change about every three or four years. Because when it is viewed to investors and obviously as an ambassador, I probably say this, but the common criticism, especially of generative AI, is bluntly and it's a thin, relatively valuable layer on top of foundational models. Is that fair or not when we look at generative AI applications today? I don't think it's fair when the C language came out around 1972.

12:09Some people say, hey, now it's so easy to build software. Every software is just a thin layer on top of C. And of course, it starts through and we know it. And the same when databases came in the early 80s. So it's not fair to think that any AI application on top of LLM is just a thin layer. LLM is a new kind of resource. It's like a new kind of infrastructure that everybody can access, sure. But then it's completely novel. It's very hard to control. You have hallucinations. It's not deterministic. It's very hard to configure. You have several knobs. You can change between fine tuning or how you prompt it.

12:44and many other, it's very hard to control. And also it changes every week. You have new LLamps coming out that claims to be better than the one from the week before. How do you decide when to change your LLM? How do you do it without breaking your existing users and product? There is a new infrastructure, there is a new game, new rules. The company was a faster to understand these rules and play along these rules. We win and build the best products. And so if we have to, sorry, I'm sure they won't understand. So if me and you start a new startup today in the travel and expense management category and we're using Whatever model we choose to use do you have an advantage over me if we're both using the same model?

13:25I think I have because I know how it works internally So I know the limitations when something is wrong I know where I should put to find a solution I also know when there are many many and more and more elements available Which one we probably be is a better suited to my problem and I know what kind of machine learning I have to build around by NLM to balance for the weakness of it. So we see companies switch between our LLMs very frequently. It's how it will work of course. You have in every two weeks, intradable things coming out of research and if you just assume it's a static in the year from now your product will be very dumb compared to your competitors products or more expensive to run or very slow.

14:05We had a mad on the show from Stability and he said, you mentioned hallucinations, he said hallucinations are a feature not a bug. I mean by construction the LLM has to output something and so if there is nothing to say, it'll make something up that looks natural so this is probably what am I meant by design, you cannot not output something and so this would be an hallucination. And you also mentioned kind of the changing nature of LLM's models. He said that no models today would be used in a year. Do you think that's right? Absolutely agree. With that, we use drives a car you drive today in 10 years.

14:42I don't think so. There is so much progress so fast that I don't see why we wouldn't use the same in one year. We mentioned your proprietary knowledge. If me and you were to start a startup in the same space at the same time, how much of an advantage is it to have existing proprietary data, say being a four to five year old company with four to five years of customer data, versus being a new startup with no existing proprietary I think this is always one train late. So having a lot of pre -operability data was very, very important for the last cycle. Five years ago, maybe it's less and less true.

15:15You need some to bootstrap your models. For instance, at NABLA, we build the dataset of the 30 ,000 medical consultations with patient concerns. We have to pay doctors. It's very hard to build this because we need these to bootstrap our product. But then with the new pre -trained models, fine tuning is very efficient with a little bit of data. There is a, I don't know if you've heard about Lima, models that came out three weeks ago. Can we actually just interrupt you and just ask for those that don't know? What's pre -trained and what's fine tuning just so people understand normal pleasure? So large language model is trained in two phases.

15:50First phase is unsupervised pre -training, so it's just fed with huge amount of text, and it's trying to predict the next world. And so this is what we call unsupervised pre -training. Unsupervised because you don't need any human intervention. The text by itself is enough because if we try to predict the next world, and then the second phase is fine tuning when you use different machine learning techniques. So for instance, brain transplant learning for chat GPT where you train your model to follow instructions like for chat GPT is when I ask a question, and you should tell me something that looks like a right answer or looks like a reasonable answer to what looks like this question.

16:31And so the fine tuning is the second phase where you give more precise instruction on how it should behave. To do that, yeah, there are several techniques. So everybody's still learning, you know, it's like huge back boxes, these things, and everybody's still discovering new things. But three weeks ago, there was a paper about Lima. This is a Lima paper shows that with only 1000s question and answer examples of very very small data sets They get something for fun use for fine tuning. So the second stage They get something that performs better than GPT -3 and almost at the level of GPT -4 with only 1000s QA you know for fine tuning so the thing with LLM is it looks like a huge Pre -training with text it's learning mostly through pre -training with huge amount of text and then with a small amount of data with high -quality data.

17:19You can get a lot, you can get what you need and train your model to do what you expect with very small data sets. And we mentioned model sound, we mentioned kind of size models there and actually how you need it, as you raise small amounts today. Will there be new foundational model companies created? Do you think or do you think we have the existing incumbents already? We probably have most of the existing companies. Many of you will So we started, there is a lot of hype and it's public so I can spill the bean about Miss Tal and you won, created by S3 engineers who took them from Facebook and I know them and you can still build this financial model.

17:57I know them too and they're fantastic but how can you do it without being so far behind? To make a successful financial model company you need intradable scientists and a huge amount of money and if you check these two boxes I think you can still do it. And you need focus. Google and Milla could have done what OpenAI did, you know, easily and they didn't, because it was not the priority and the resolve with legal people around. But I think a new startup with enough talent and enough money, and when I say enough money, I'm talking about billions, just to be clear, then I'm sure you can do at least as well as OpenAI.

18:31We mentioned incumbents. We mentioned startups that kind of encroach your own incumbent space. I think the big thing I think, Madness, like, who wins in this next wave? Is it startups? creating amazing new products, leveraging financial models. Or is it actually Adobe? Is it actually Apple? Is it Google with Bard? How do we think about where value occurs to start up or incumbent? So incumbents have a huge advantage through distribution. That's the one thing that is hard for us startups. But incumbents have many disadvantages. I think first they are very slow. You mentioned Adobe that was sure you would because it's the one example that everybody has.

19:07but then who else is what's as fast as I'll be? So I think most of the incumbents won't move fast. And in many cases, do you not think they're moving fast? I mean, I don't know if you call notion in incumbent, but notion of move very fast. Adobe move very fast. Navan, travel, experience management company now, is like solely on way of an AI. I think actually they have moved very fast. That's fair. Some of them can move fast and it's not fair to say they are slow and that's it. I think the income and suffer from problems because in many cases they will do AI -enhanced features and this is what all the one you mentioned did.

19:45The notion you still have a document, you edit it, you have a cursor, the right L by the way you can call chat GPT and to summarize a paragraph is what I call spreading a little bit of AI dust on the magic dust on your existing products. Who knows how differently you can think about building knowledge for your company, probably something will come and destroy notion and Google dogs and all of them with a totally new paradigm that is made possible by AI. Certainly these incumbents won't do it. So I think the best incumbents can benefit from AI to be competitive in their existing markets, but I don't think they will invent the totally disruptive things that we killed, something like Kodak invented the digital camera, and of course they never released it because it would kill their main and I heard from you, which was the films.

20:32You think that's why Google didn't innovate in the way that they could have done, because actually the cost per query, like ChatGPT does, is so much more expensive than the way that they do it today. And actually it would have cannibalized the whole business if they were like, hey, let's embrace this new cross structure, which is so much more expensive. I think the reason is simpler than that. The reason is nobody could predict that LLMs would be so useful and powerful before you try to run at this scale. and who in the Google All Chart had the incentive to invest $500 million and just to see this without any business benefit for the company.

21:08If you add to that the legal department who is not that happy that you are like releasing random childbugs we can say anything, then nothing happens. And this is what happened to Google and probably also at Meta where nobody has the incentive to do that. And so OpenAI has a private company they need to show something to build products and they have this curiosity and the financial power and they did it. We look at the different approaches. There's the open approach. There's the closed approach. We mentioned some of the biggest names there. You mentioned the Yang and the Koon episode. He obviously is a big proponent for open.

21:42How do you think about which approach dominates over the next few years open versus closed? So obviously I think the foundational model that will win will be open. But that being said, you know, we should be careful because even an open model trained with open data, to me, is not that open because when you have like 300 billion parameters and it's a huge blibers, you don't understand why the output is what it is, is it really open? And so I'm just putting a little bit of salt on what I hear and like open models are you understand everything, it's explainable, it's predictable, it's not true, an open model can be as hard to predict and That's a close model.

22:21We mentioned data sets before, and I do just want to touch it, because I think it's important. And I am, as you imagine, Eman's absolutely. He said about the importance of national data sets. Actually, for certain things, I think it really is actually very clear. Do you think we'll have national data sets moving forward, given how different nations have such different data? I'm not sure about national data sets. If you want to set something into a nation, it's good to say that, but more per industry, per vertical data sets, of course, would improve the quality of the novel. So if you train an LLM only on medical data, you get a better LLM for medical applications, but even if you feed the LLM with curated data, it's not guaranteed that the output would be good, would be perfect, that you can trust the output.

23:03So feeding a LLM with trusted data doesn't make the output touchable because of how LLM works. So there's a lot of misconception about this. How may understand that then, because I think a lot of people that will miss on the sound, so you have great high quality trusted data. What leads to then high quality output and good decision you're now coming. So, NLM is a huge probabilistic machine. It's like a autocomplete. I think this is the best image. And it will complete the beginning of your sentence at any cost. It will always complete it. And you may have like 10 sentences, let's say, in the input dataset that are true.

23:35But maybe the LLM will start with the beginning of the first sentence and switch to the end of the second and other sentence just because it looks good. But logically, factually, this output will be totally wrong. And I simplified a lot, but this is exactly how it works. And the form is perfect. It always looks like sounds like very good answer, but the reasoning, the facts may be totally off -invented or wrong. And even if the input dataset is wrong. So when people say chat GPT gave me a wrong output because it was strained and read it and read it is a lot of noise, yes, but only partially. Even if you remove read it from the training dataset, it doesn't mean you won't have random answers.

24:15We kind of jump here around from Imhad to Ian and picking different ones, but Ian said in particular that it's a big jump to assume there's a correlation between intelligence and the desire to dominate. When we think about the most common question being the fear of AI really overcoming human power and dominating us, how do you think about Ian's statement about that correlation? Do you agree or disagree? And how do you think about that? I fully agree with Ian. I think if you really understand how machine learning works and you're not looking for free publicity. I don't see why you would say something like that that getting more intelligent will make them want to kill humanity.

24:51I don't even understand the best leading to this thinking. Why does someone like Jeff Hinton then feel like? I'm not in the head of Jeff, I don't know. I don't know and I know Jan is also surprised. Do you think Elon Musk's decision to be very proactive in terms of the petition to pause AI development? How do you think about that? It's trying to build a team to compete with OpenAI, hire somebody from DeepMind, like the same day where he announced we should post for six months and it looks to me that the people who are popinant of this post or to more recognition, other ones will feel that they are in advance and so it's like a way to say, guys, let us, we are in front, I don't want more people to start the race.

25:33Can I ask you, you mentioned creating chatbots 22 years ago and kind of the length to where we are today. I always think it takes longer to adopt than we think. Blunt me, when we look at where we are today, are we really at the precipice now? Or actually, is it another 10 years before we see that adoption cycle? Finally it's here. When I see people using touchypt and learning to do with a jump differently, with a help of touchypt, I really feel we are on the verge of finally having a huge impact with the chatbot. For the first 10 years, I tried to convince people that chatbots were ready and to buy my chatbot, and they say, know it's not and then for the 10 following years people told me our chat about the incredible we can replace human with chatbot and I said no no no no don't do that it's not ready and finally now I feel we we are at a point where many things will be impacted.

26:21Patchelbot which doesn't mean you're replacing people with them it's a great tool but it doesn't mean it should because of the chat form it's tempting to think okay let's just replace this guy this worker with a bot and many cases I don't think it's ready for that but it's still You'll have a huge impact of how work is done. He said, as door ready to necessarily replace, when we think about an Aber and healthcare, I seem to be crossing the lot, but E -MAD with AI, you can change the nature of a doctor. Will AI replace dotes? AI will not replace dotes, but dotes who use AI will replace dotes who don't.

26:54Definitely AI can have a huge impact on dotes or where they work. And those who will embrace this change will strive. Can I ask you the next one two years, how will those dotes who embrace it? How will they use it? The first thing I learned when I started to operate a healthcare company is that for the first 50 years of computerization, computers have been a bad news for doctors. Before computers, they see patients as a care, there is a little bit of admin work that is done by somebody else and not so much paperwork and they're very, very, very happy. And suddenly, people like us come to them and say, okay, now there is an electronic patient recalled.

27:30You need to document, you need to feel this form, you need to do this and that and we have trouble to get the money from the insurance company so we need to document more to make sure the claims go through and so on and so on. So, you know, the other day I visited a small clinic in Paris and all the doctors looked very happy and I said, what happened, you know, it's not long. Well, the computer system is down today. We are just using papers and pen and they were so happy all of them. And so you have to realize that the state today is a very bad state where computers were bad bad news for them because they are drawing under this I mean this such a work documentation for many reasons.

28:08Doctors spend on average 49 % of their time doing this kind of I mean this creative task as opposed to caring for patients. It's bad for everyone, it's bad for them. Three out of four doctors suffer from symptoms of burnout. It's bad for patients. Three out of four suffer from burnout. Yeah, three out of four doctors have suffered from burnout symptoms and for the last year. And the main reason of this is they all mentioned the pressure of all these admin work, basically. What is that admin work? I didn't know this life. The biggest work they have to do is clinical documentation. So they have to document everything they hear, their decisions, and in big systems that we call EHR, you know, electronic has records, we're talking dinosaurs or systems.

28:53And the reason they need to do these documentation more and more, first is the financial reason to get rain boars by the insurance companies, especially in the US, you need to have like a very solid file with all that. Otherwise, the insurance will take the first opportunity, the first protects not to pay your claim. The second reason is for legal protection, because medical malpractice trials, you know, it's so expensive, your best protection is to document this in the right way. And so this is why mainly I mean, work started to grow bigger and bigger. and these EHRs are very, very old and clunky systems.

29:27I checked the other days, there was one specific technical action that took 227 clicks, mouse clicks, to be performed in the system. And I posted this on LinkedIn and many doctors answered and said, no, it actually is more than 300 clicks. And so this is a stage today. So, what we look at that, though, and the thing that strikes me there is like, okay, we could actually have recordings of meetings transcript, speech to text, and then also suggestions, meaning summary notes, whatever we want to do. Travel is its healthcare data. It's not me and you chatting about shopping where we could have preferences, normally gives a shit out, she said, March about what you want to buy from a supermarket.

30:03With healthcare data, does regulation and consumer protections get in the way of efficiency? Yeah, so at first the solution, I think AI will impact doctors, we could bring an AI assistant to every doctor to every clinician. This AI assistant will be aware of what's happening, what the patient is saying, what data we know about these patients, what the communication, what work needs to be done. Sorry, just to break it down. How does it know what the patient's saying? We were called meetings. We don't recall the meeting, but we capture the audio, we tell stories, we just capture it and then drop it.

30:35And so yeah, it gets a lot of context from the audio environment, what we call an ambient system. And the data itself from the consumer. How do we do that from wearables, how do we ingested data? So this egg assistant is connected to the EHR. So it will get a data from the existing source of thrills, which is this patient's record. Are the EHRs interoperable? Do they have the ability to move data between different applications and silos? So in theory, there is a new law in the US. In there, you know, epic spend billions to millions to try to block, but it finally was after I think 20 years of battle was passed, And so, yeah, there should be inter -rebole.

31:15Like the new model near Charles are like CRM systems today. They have an API, TC20 grade. Can I ask, I worry with healthcare about the incentive mechanism. And what I mean by that is that specifically, if we make people much more productive and we maybe remove the need for certain nurses, actually more people will be unemployed. And when we think about politicians who are allocating money for the NHS, which is obviously our healthcare system, they need nurses' votes. And so saying, hey, we're going to remove a load of low -level nurses through intelligent automation workflows, whatever that is.

31:49It goes against the political incentives by being more efficient. Does that become a problem? It's not a problem. The World Health Organization says that we are missing 18 million clinicians by 2030. So the state is not, it really put people out of the jobs as the reality is we are desperately looking for clinicians in every country in the world. So if you can make their lives easier, it's a big win for everyone. What are the biggest barriers then to AI having the impact on healthcare that I think we both believe it can? There's a many barrier. I think the mistake that many startups are doing in healthcare and what we did initially is we focused directly on the patients.

32:29It's too much too fast. You know, you cannot jump. Healthcare system is so complicated. You cannot regulation, you know, for many, many reasons, you can do that technically. We're not ready to do it. We don't have the data. We shoot first focus on clinicians, the way things are done today change your life with AI and then together We'll go to the next step. So I think to answer your question that one of the main problem is that we are trying to go too fast to patient -facing perfect system as spending a lot of time in hospitals I spend in nights in the emergency Services call center in Paris. This link to everyone.

33:00It's how is that? What do you see? So it's interesting I met a doctor in a cafe in Paris. I met a demo of Nabla on my phone and he told me, Alex, you're going to come to the emergency services call center next week all night with me. He turns out this guy where he's like the chief emergency physician in France, Patrick Poulou, invited me to spend nights over there. What I learned, spending nights over there, is it's a little bit like a call center. You have a first team he's taking calls. Overall in France, it's about 40 million calls a year. And the first responder, they don't make medical decisions.

33:33They are not doctors, they are not even nurses. The goal is to just to understand what is the address and what is the situation. What is the emergency? It's very hard to get that because people are panicked and you have lots of people calling for very small things, really close things, and you have real emergencies hidden. So the job is to sort through this very, very complicated situations when people are calling and they actually write a note, structural note with this information. They click submit, and then you have like regulation doctors who make the decision should we send the real emergency services should we send the firefighters or should we just have a doctor to this person over the line and so it's a two -step decision and a lot is done around documenting this situation and this thing you know is would be so easy to do with what we do at NABLA and you know what we know how to do with AI today the goal would be to keep the person who is answering the phone because because they are know how in terms of empathy, calming people down, understanding the context, very complicated situation again.

34:34Typically you have several people, there's screaming, nobody knows how many victims, what's happening, very, very complicated situations. And these people, I spent hours and hours listening, we'll head for them next to them. They are expert cutting through this darkness and understanding what's happening. So we want to keep these people, but they are typing with two fingers on the keyboard and missing some information. It takes a lot of time to get. And so having an AI assistant work alongside them listening to the call and documenting. I tried it, you know, it works already perfectly with what we have.

35:04It would be a perfect team. So you see an example. How many of the calls lead to ambulance sent out? Do you have that number? Is it that one in ten, one in twenty? What I saw the few nights, you know, maybe one in five results in services being sent. And in this case, three and four are firefighters who have medical doctors and so on, but they don't handle the most critical medical agencies are handled by 20 -gold Samu in France, and it's one in four. How receptive are doctors to when you talk about AI and then prove that they work with AI? And they're like, yes, bring it all the life, huh, see that before.

35:40So we've seen a change in that in the recent years, and up to three years ago, almost every doctor would tell me, okay, you don't understand our problems, go away. I'm already fighting against my EHR every day, I don't mean more stuff and it really changed recently. The core reason has nothing to do with AI is that the health systems are collapsing everywhere. You know, I know the situation with NHS here. It's worse in France, in the US, all the major hospital groups are losing money. Why there was a France? So in France we have a huge shortage of doctors and there are zones in France where you have to drive 200 kilometers and wait for three weeks just to see a GP.

36:17So this is obviously a problem. Global Ease of the problem is the same everywhere. It's access to healthcare. In France, you can get good doctor quickly if you know somebody in the system. In the US, you can get it if you have a lot of money. It looks different, but eventually it's a problem of not enough doctors. And their last doctor's never, or are we getting more unhealthy than ever, is the demanding increase or is the supply decreasing? Both since it takes 10 to 15 years to train doctors, decisions you made 20 years ago have a big impact today. So first there are less and less doctors. Many of them are aging and we go be retired soon and so the number is going to drop.

36:53And in terms of demand, everywhere in the world you have a huge rise of chronic disease like diabetes that takes a lot of medical resources, you know chronic disease. We always see as engineers, young healthy people we see that like easy things with medicine where oh I'm hurt, I go there is a quick diagnostic decision, maybe I spend two days in the hospital and then it's over, but what takes the resources in the healthcare system is not that is our aging people and chronic disease and often combined. I actually had a fascinating stat, it was like 90 % of the cost of healthcare, it's been on the last six months of life.

37:27Can I ask you, my first ever investment in fund -fight was like, what's that for doctors and nurses in the UK? They were 100 ,000 doctors and nurses in the NHS, and then it came to getting paid. And they just don't pay, and they would deliver great that 100 ,000 dollars and losses. How do you think about actually building a business being able to deliver value in a sector that just doesn't pay and doesn't have a willingness to pay? This is the biggest difficulty when you are trying to disrupt healthcare, especially for startup. You have the bear insurance or public bear. You have the providers who are providing care and you have the patients and it's a very complex relationship with three parties and typically the one who benefits from our product is not the one who is paying for it.

38:09So typically the patient will benefit, for instance, from your better SK app, but it has to be paid by the payer, by the NHS, and the provider disagrees. They can block everything. So you have to solve this three -mass problem from day one, which is very, very, very complex. And so you have to find a balance between, as a startup, if you optimize a very small process, it's easy to deploy because it follows the lines of the existing system. So, for instance, if you do a better way to take appointments, online appointments instead of calling you don't change a Husker system with that. Even that is hard to push but it's easier because you don't change the fact that there is an appointment, there is a consultation, there is a synchronous visit so you fit into the system.

38:48If you do something too ambitious it will never fit in the system. It's I think it's impossible to go to market with something too ambitious. So I think as I thought as we have to find the right level of ambition where it fits enough in the system to be adopted but it's not too much disruptive from day one otherwise he's impossible to go to market. And he pays you. So they're very hard lessons. If you are thinking about trading a headscar startup, the very, very first question I want to hear is who is paying for the product? Who is paying? What is the business model? Then you can in the startup, you know, in YC and all startup schools in the world that tell you don't start with a solution, start with a problem.

39:27But in headscar, even starting with a problem is not enough. Start with always paying and then how do you do frames or problem for this person to pay and then what is the solution for this problem eventually. If we think about this respond to the cool though and we take intelligent notes which allow them to be better and more empathetic who's going to pay for that the hospitals don't pay. So in emergency services the only potential payer is the government and so not a good good good good to market you know. Yeah this is first good to market and that's why I didn't start with that now you know we've deployed our product in the US thousands of doctors are using it every day we are well -funded now if the emergentism is in France we really want my product and the sponsor is Patrick Blueis like the god of emergency in France and Mr.

40:14Affairs look at me the eyes that say we rewant it it may be the right timing but it would be very very bad idea to start with that as a startup and maybe if you're lucky you do a pilot and then you wait and you is what I call DESPI pilot. And you go to the US and you sell the private clinics. We sell it with the US because the problem we are solving now of clinical documentation is huge in the US, big girls in Europe. And so the willingness to pay for the existing providers, and again, you need to, at entry points in the system, is very high. We found this go -to -market. We also made it possible for physicians to use our products without any approval from anyone bottom -up.

40:53They can go to nabda .com, you know, it's a web application, it's a Chrome extension, they use it tomorrow and then they love it and then we'll talk to their boss and say we like to use this in the full clinic. Can I imagine there's the US there because the bigger market. I think there's a common suggestion to a lot of AI founders today that if you want to build an AI, you've got to be in the valley. It's all about being in San Francisco. It's where the tunnel is. Paris and France has become also an AI hotspot. How do you advise founders first on whether they need to be in the valley or not to be building the best in AI.

41:24I think it used to be true, but it's not true anymore. When I built my second company with the AI, I happened to stumble about Open Add -I'm Shayer, the creator of theory, packing a lot in the valley after an event, and he helped me a lot to think about with the AI, gave me the confidence to follow what I had in mind, and owing to this confidence I was able to refuse referrals from Google and others who wanted to buy us too early. And so it had the huge impact on my company. If I were in Paris, no ad I'm share, nobody has done this before. Maybe I would have sold it to the first 10 billion. Okay, let's sell it.

41:57It's good. And so it used to be true. I think that you needed to be in the valley with having these kind of people around you. No, I think it's less true because everything is distributed. The talent is very, very distributed. It will get more distributed. And I think you should get close to your customers. Given French startups still sell to the scene? Yes, French startups. So in France, you have very good AI engineers, machine learning engineers because the education system is free, is very focused on mathematics. So we produce lots of good engineers, but we suck at growing companies. Really, we are not better at that.

42:28I don't know why. Maybe we like discipline, maybe we... Is it you suckers growing companies or you just sell to see? They also comes in and actually 50 million. It's a lot of money. If you raise one round, you'll take him 10, 15, each is co -founders, say, bowl. Exactly, say, bowl, it's enough. And so if are normal it's hard to refuse a 1 billion dollar offer if you haven't done 10 million before. But this is what Zuck did, what Google founders in SEGA and Larry did. So maybe we're not focused enough or disciplined enough and we don't have examples around us to grow this company. Hopefully it's changing.

43:03We have very good scale -ups in France now but it takes some time to. What do you think Europe needs to do to keep pace with the US in terms of AI and being an ecosystem in the last day of the day. So Europe is probably 10 years late compared to US and China, and with a new regulation, we are probably going to take 50 years more. Talk to me about that. What do you think that is? Because the regulation is so prohibitive, unpack that for me. So the new regulation is the disaster. If you look at it, people wrote this, they went too fast. Good regulation is about good timing, and involving the right people who are actually doing stuff in this domain.

43:40I think Europe being late felt like, let's be at least first in regulation. What was it about the regulation which made us so bad? Some aspects say for instance that you should be accountable, I'm simply saying that you should be accountable of the all the data you used to train your mobile, for instance. You should make sure that you have a proper license like explicit consent from everywhere it comes from and I see why it's a beautiful idea. Who would disagree with that but in practice it means one of the percent of the LMs that were trained in these last three years would be illegal in Europe.

44:13It's not connected to the reality. The intent is good, but the limited puts on how to train a model and how to operate a model makes it in practice compared to what we do today makes everything illegal. What do European startups do then? We move to the UK. Maybe for one reason Brexit? Maybe the UK. Yeah, finally Brexit is, maybe it was good. You know, I'm have to working if the regulation, if it's really like this and nobody can challenge it, startups like us may have to move. Or maybe you can keep the team in France but we have to physically train the models elsewhere, I don't know, it's a big huge danger.

44:45What would you do if you were in charge? If I put you in the hagg or in the EU and you were given the regulatory powers over the next five years of AON Europe, what would you do? First I'd wait a little bit because it's too early, we are still in a demo phase of AI, you know, LLM since not really used a lot in just beginning to be used. And as I said, you know, The regulation timing is key, it shouldn't be too late, but if you're too early and nobody knows what actually are the risks, not the risk you think because you read some science fiction books, but the real risk nobody knows yet. And so I think first I would wait maybe a year or two to learn from the field what should be regulated and why.

45:23And then I would involve people who build these models, of course, but also people who are using it, the users, the general public, which was not done so far. So they have like experts who are smart people, but there is no reality of any lens yet. What do you think about China? We spoke about Europe back in China. How do you think they've embraced AI in the next wave of AI? They have a key advantage that there is no GDPR or very few regulation internally and so the data qualities they have in the amounts, both the quality and quantity of data is incredible in China. And so for instance for healthcare data, they probably have everything about every individual in China.

45:58And if you're supported by government, I'm sure you have access for research to all these. They are lucky for that. If you think about geographies, who's the winner and who's loser in the next 10 years? China, US, Europe. They all have issues, they're issues. We talked about the advantages of China, but they are very close. They are getting more and more close. They have maybe the wrong incentives at the research level. It's hard to predict when we'd come out of China. We talked about Europe where regulation is probably the biggest problems that will keep you behind. And we are already behind that's my concern.

46:32The US is always in a very good position. The immigration laws may be something that will be a problem eventually in the US because talent is so distributed. We can learn deep learning very easily from everywhere in the world on a tablet today. It will be more and more like this. And if it's so hard to go to the US, to work for US company, eventually it will have an impact. I think I want to move to a quick fire run. I say a short statement, you give me your immediate thoughts. Does that sound okay? Okay. Okay. Do you agree that some of the biggest businesses to be built in AI will be built in services businesses helping enterprises implement AI?

47:06I disagree AI will enable a new generation of players in every industry that we use in combative and truly. What do you think is that time scale? Five years existing services companies like consulting companies are embracing AI is it will eventually remove the big data from their website and put AI and then we put an element to replace the world and say, they will take this business, I think. There was a company called Element AI a few years ago in Canada, a very ambitious company would try to do services like that and they eventually failed, they were acquired by Service No 4, so their months are raised.

47:38What was the biggest element you'd like to change about the AI community? Making more diverse, I'm really tired of talking to people like just like me. It's a cliche to say that but it would be a lot of value if we get more diverse. I have another quick anecdote. When I was at Facebook, somebody discovered that the model that was supposed to tag images that was one of the person successful to finding tennis balls in pictures. Actually, if you remove the tennis ball from the picture, it was still finding the tennis ball. So it didn't learn to find the tennis ball. It learned the context of a tennis ball, like a racket.

48:10In the second phase, it changed the color of the people on the picture. And if you had more black pixels in the hair, suddenly the model thinks, oh, it's a ping -pong ball. It was a very early days when we discovered that some models have bias. And this is bias in this case, it didn't learn to look at the ball, it learned to look at the race of the people around. And it's actually making this decision tennis versus ping pong based on the race of the people around. A man said all models have bias, is that fair? Yeah, more or less, but all of them and many models have huge bias. The guy, you know, very strong researcher, who found this thing in Facebook very, very early before everybody talked about bias.

48:47is the Mustafa CSA, is from Senegal. I don't think it's such a luck that somebody with a different angle than we have, different culture, found that a huge hole in the malls that we hadn't found before. Does AI kill traditional media? I don't think AI will kill investigative journalism, finding the right sources, the right information. So this part of media, I don't think, will be replaced by a now -to -generation part at the output, probably will be disrupted a lot by it. Was most painful as Niveland you're also pleased to have learned that Fundamentally people don't really change what may she say that I mean you can help people to grow It's true for yourself So you can correct some weaknesses you can be stronger at work where you are strong at already But I think you have to accept that some of the fundamental characteristics of yourself and the people around you won't change And if you expect them to change it leads to big fader and mistakes What do you think is the biggest misconception that people have around their eye?

49:48You hear many discussions. What do you think of that? I can't believe they're saying this again. It's that they think it's conscious. They are influenced by the form, like, oh, perfect answer. The perfect form needs a chatbot. It answers my question and influenced by the form. They make conclusion on the deep inside of the system and say, oh, it's conscious. And for me, the biggest proof of that is that in 1966, when the mother of all chatbots was released at the MIT, you know, Eliza, the very first bot. For a few months, people around the world thought that AI was solved, that there was a human, you know, sentient AI in Eliza, which is a very, very simple pattern matching system with regular expressions.

50:31But because of this, the way it was presented, people fell in the trap and I think we keep falling in this trap again and again and again for 60 years. What's the strongest belief you had which turned out to be wrong? It's very hard right here because when we change belief, we tend to forget that we have the contrary belief before and... For me like with Panda it was funny I thought like if you showed enough value you would get people to pay. If you could prove value you would get payment. Yeah it's a very good one and we had exactly the same restriction at the beginning of Lavela when I thought if patients love your healthcare product enough and you prove the health benefits of your product, then payers will pay for it.

51:11And it's not that I'm saying it's so wrong, it was obvious but probably a big belief we had that was painful to an expensive to learn. He's been the most helpful angel. Probably Jan Leuka, especially when we doubt about something or is there a confident that we are under right pass and it means a lot. What made the best VC? So I worked with Andreessen Arvitz with my previous startup. it was incredible because they never called, they never asked for anything. We didn't even have a ball meetings and every time I need something in a 20 minutes I get huge help. Maybe it's to find a real estate problem because I don't have a naffice.

51:47Maybe it's organizing a huge event and I don't want to hire a marketing team. I want to use them for one week. Or I have a strategic decision to make and they give me access to the best people in less than a day. And so the fact that you are control and you ask for help and deliver it we could go with the AI to a very nice company with only 13 employees because we are relying on 100 % of these things. It was incredible but for my first setup I did some strategic mistakes, go to market mistakes and then I wish my VCs back then would have been more involved with me and coach me and it really depend on the founder structure.

52:20A neutral VC with not here is much better than a bad VC we can have a net very negative impact on funders, I'm helping funders every day. Do you think this in Europe is good? Or do you think it's still massively behind? You've seen the US. Again, it changed a lot. So 10 years ago, VCs in Europe were all from the financial industry. There is nothing about financial industry finance in being a VC, a little bit of course, but it's mostly about entrepreneurship. So 10 years ago, all the VCs I was working with in the US were former entrepreneurs and all the VCs I knew in Europe were former bankers.

52:52In most situations, you don't need your VC to be a banker, but you need them to be an excellent entrepreneur. Tany is time, Wes Healthcare. Hopefully, ten years time, you know, every physician has their AI assistant doing a lot of stuff for them and helping them to be ten times more efficient, you know, seeing more patients, spending more time with every patient, making better decisions. I also think that I have the higher level decisions that require a big picture of the data, you know, large, large view will be taken by AI, not by people. So, for instance, in an emergency services regulation center, when you have thousands of people leading help and you have some resources, what is the state of your resources, what is the demand, how you make these decisions at the TT scale.

53:34Today is done by humans, but it's a miracle that it doesn't collapse. And sometimes it's collapsed when it would be events. 2033, where are you then, was Alison? So my dream is to build a healthcare system from scratch. Without any of all these limitations and constraints we mentioned. So controlling full stack, patient experience, provider, hospital, data -driven prevention. So my dream is to be able to build that and to do that I still need to learn a lot in healthcare and I need a few billion dollars. And this isn't I would love to end this. Thank you so much for joining me and thank you for putting up with my prior questions.
